I just installed gomtree, and read my xattrs: looks very promising! Thank you for the suggestion. :)

I'll read up on "post-checkout hooks" to see how I can integrate this in my git setup.

In case anyone's curious, here's an example of gomtree's output text for a file annotated using `yt-dlp --xattr`:

Values are base64-encoded. Nice.
